Apps available for ipad but not for ipad mini?

I have an I-phone and want to use some of the same apps that are on it on my new ipad mini but I can't pull them up. According to the info on the app it's available for the ipad but the app only shows up under the iphone on my computer. I tried searching for that app in the store on the ipad mini but it doesn't come up. Am I doing something wrong or do I just need to be patient and wait for the developers to do whatever they need to do to the app so it's available for the mini? A couple apps that I want on the ipad mini are everything (list app) and SimplyUs (shared list, calendar).

Apps available for ipad but not for ipad mini?

To get some of the apps that are on my iPhone 5 on to my Mini I went through the App Store on my iPad Mini and clicked on the tab at the top that says "not on this iPad" and hit the cloud icon next to the apps that I wanted. All apps were then successfully installed on my Mini. Here's a screenshot from my Mini that shows some of the apps from my iPhone that I don't have on my Mini currently. If I click on the cloud the app will work on my iPad Mini as well.
